Kubuntu 17.04 has been released on April 13th 2017. This review introduces some aspects of Kubuntu from it's appearance, memory usage, to default software and customization. It's surprisingly more lightweight in memory use than Ubuntu Unity, with gorgeous and Windows-like look, with complete default applications. This Zesty Zapus release is a good start for any new user to choose Kubuntu as daily OS for personal and collective purposes. Enjoy Kubuntu!

Look at the bottom panel and icons on wallpaper. You may add shortcut icons as many as you like on desktop (and also on panel) easily.

Menu

This menu can do search for installed applications, your folders, and you files (yes, with content-based search).

What about Super
key? Yes, Kubuntu 17.04 supports Super key to open/close the menu by default. Surely this is more Windows-like and favorable for many users.

What about
hot-corner? It’s still available but now it’s located at
top-right corner not top-left anymore.

What about desktop
effects? It’s activated by default and still configurable from
System Settings.

2. Wallpapers

Kubuntu 17.04 did
not hold any wallpaper contest so it doesn’t bring any new one this
time. But this is the only one wallpaper available.

3. Memory

After freshly
installed at idle time, Kubuntu 17.04 consumes around 400MB of RAM.

Total

It's around 380-400MB of RAM at idle time.

Details

From Kubuntu running on my ASUS X44C 2GB, at fresh idle time, the most consuming processes are plasmashell (~100MB) and kwin_X11 (30-100MB). plasmashell is the program that runs the whole desktop, while kwin_x11 --as its name states-- is the drawer of each window frame/decoration, and both of them are part of KDE Plasma.

4. Default Applications

Kubuntu 17.04 ships
with complete set of daily applications. From mainstream
desktop needs such as LibreOffice and Dolphin, to KDE Telepathy that
supports many messaging protocols, until KDE Partition Manager to
help you format/resize disk partition.

5. Repo

Kubuntu 17.04 uses
the same repository as Ubuntu 17.04. So it provides more than 70000
packages you can install anytime. You can search/install software
available using Plasma Discover app. This Discover on Kubuntu
holds the same position as Ubuntu Software Center on Ubuntu Unity.

Discover

Installing Software

To install software
in Kubuntu (for example: VLC Media Player): run Discover first
> do a search for “vlc” > then press its Install button >
enter your Kubuntu password. Make sure your internet connection is on
and let it progressing. Once finished, you can access the installed
VLC from menu. This modern method makes software searching and
installation easier for end-users.

Sources.list

The sources.list
content is all the same zesty as any other official flavor.

6. Audio/Video

By default, Kubuntu
can play OGG, OGV, and WEBM (open formats). To play MP3 and MP4,
Kubuntu needs additional programs to be installed. If you need one,
just install VLC.

7. Documentation

Kubuntu 17.04 ships
with offline and online documentations. The offline one is
preinstalled, you can access it from menu > Help. In this Help
Center you can read every help for every KDE Application, plus
command line documentations (UNIX Manual Pages), and also GNU Info
(Browse Info Pages). And, the online documentation is available at
http://docs.kubuntu.org.

8. Customization

KDE Plasma, the
desktop environment Kubuntu uses, is well-known for being the most
customizable desktop on GNU/Linux. Thanks to KDE System Settings,
Kubuntu desktop appearance and behavior can be changed easily by
mouse clicks.

In “Window
Decoration” section for example, there is a Get new Theme
button. This connects you with the KDE online repository so you can
search and install many themes available.

Shortcut Keys

You can make any
shortcut key as you wish easily using System Settings. Access it from
Workspace > Shortcuts > Custom Shortcuts.

9. Daily Life

Mainstream desktop
purposes are already fulfilled by Kubuntu 17.04. You find here
LibreOffice for your documents, Firefox and KMail
for browsing and emailing, Discover to find software, and the
full featured file manager Dolphin to handle all your files.
Furthermore, here you have the complete & user-friendly System
Settings, the ability to compress & extract ZIP/TAR files
using Ark, and you have decent disk management tool like KDE
Partition Manager. It’s really a complete OS for daily desktop
needs.

File Management

Kubuntu gives you
the complete-featured file manager, Dolphin. It has all basic
file management features, plus split view (F3) and multitab, support
for MTP and tree-view. One of the most awesome feature is built-in
terminal (F4) so you don’t need “right-click > Open in
Terminal” anymore. Dolphin is very configurable and flexible, the
best file manager you can see on GNU/Linux desktop.

ZIP & Archive
Files

This is Ark opening
a ZIP file of Android Studio. You can also create ZIP file by
right-click > Compress > select ZIP format on Dolphin file
manager. Plus, Ark can also open any ISO image file for you.

KTorrent

Ubuntu features
Transmission, while Kubuntu features KTorrent. This is the gorgeous
BitTorrent download manager from KDE. While you need to download any
GNU/Linux distro, audio & videos, or another big files via
torrent, KTorrent is always ready for you to use.

10. Commercial Support

Kubuntu 17.04 offers
commercial support via Emerge Open at
http://kubuntu.emerge-open.com/buy.
They say at the web page “… a team of dedicated full-time Kubuntu
experts able to advise, consult, implement or fix any Kubuntu related
requirements ...”.

Conclusion

Kubuntu 17.04 is a
desktop OS that’s ready for daily use. It has lower idle memory use
(400MB) than Ubuntu Unity (1GB) or Ubuntu Budgie (850MB) and offers
Windows-like interface & experience, suitable for those migrating
from Windows. Its default applications are complete and
desktop-oriented, with good support for desktop customization through
System Settings. The software installation is pretty easy using
Discover, and this will be a new thing to explore for new users. I
can recommend Kubuntu for any user using computer with 2GB of RAM or
more, but not below. Be happy with Kubuntu Zesty!
